App Servers

Application servers and scripting platforms like ASP.NET, WebLogic, ASP, WebSphere, PHP, ColdFusion, JSP and Perl. These technologies deliver dynamic Web sites, e-commerce, and most Internet-based software applications. Port80 Software launched the industry's first survey of application servers and scripting platforms used on the main corporate Web sites of the Fortune 1000 in May 2005.

This survey analyzes HTTP header signatures to determine the presence of an application server or scripting technology, and since some servers are configured with more than one backend (for instance, classic ASP and ASP.NET) and/or have no application server present, the percentages above do not add up to 100%.

However, this survey does discount for duplication within categories. For example, a site running ASP, ASP.NET and WebLogic would be counted in both the Microsoft (ASP, ASP.NET) and Java (WebLogic) Platforms categories, but the site would not be counted twice for the Microsoft Platform, even though it is running ASP and ASP.NET. This method of categorization attempts to give credit for all technologies deployed on a particular Web server while not "over counting" multiple instances of the same technology family.
